I'm not sure why apt-listbugs didn't howl when I upgraded to 0.8-1.2, but so far, I haven't been bitten by these bugs - I guess that I've been lucky. In any event, when I originally wrote 's2disk', I really meant the in-kernel suspend-to-disk functionality, which can be invoked in various other ways. Moreover, in the most common use case for suspending, where a machine will be disconnected from its external power source, it's not a great idea to use suspend-to-ram without a working suspend-to-disk backup, since if the internal battery drains before the external power source is reconnected, the system will crash, with possible data loss, etc. Celejar -- foffl.sourceforge.net - Feeds OFFLine, an offline RSS/Atom aggregator mailmin.sourceforge.net - remote access via secure (OpenPGP) email ssuds.sourceforge.net - A Simple Sudoku Solver and Generator -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

Thanks, I managed to successfully - install uswsusp - configed /etc/uswsusp.conf - did update-initramfs -u and s2disk preserves the system and shuts down fine. However, on turning on the machine, everything goes back to old routine and does a normal boot, instead of resuming from my suspension. What I've missed?

It looks like the kernel / initrd isn't properly configured to use the resume image. I'm not really expert on this stuff, but please post: a) your uswsusp.conf b) (relevant parts of) the dmesg / syslog from a boot after a suspend Celejar -- foffl.sourceforge.net - Feeds OFFLine, an offline RSS/Atom aggregator mailmin.sourceforge.net - remote access via secure (OpenPGP) email ssuds.sourceforge.net - A Simple Sudoku Solver and Generator -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

I didn't spot anything relevant in /var/log/dmesg or /var/log/ syslog. Could you post yours so that I know what to look for pleae?

What does you kernel line look like in your lilo/grub1/grub2 configuration. I think it may be helpful to have a resume= argument there somewhere. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss(a)iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/ |
